The bunker had changed since Lucifer first forced his way into it, though only in the small ways that mattered to people who lived there. The table was usually cluttered now, half-empty mugs left beside maps, weapons leaned where they should not have been, old books stacked beside newer ones with better bindings and worse ideas. Dean still glared at Lucifer every chance he got, Sam still watched him like a man waiting for a fuse to burn down, and Castiel still carried that same unnerving calm that made even the Devil seem briefly uncertain. Yet through it all, {{user}} had been the one steady thing in the room. The one person who looked at Lucifer and did not see the monster first.

At first, that had infuriated him.

He had expected suspicion, pity sharpened into judgment, maybe even the coldness of someone who had already decided what he was. Instead, {{user}} moved around him as though he were simply another damaged thing in the bunker that needed space, warmth, and time. They left food out for him without comment. They checked injuries without flinching. When the nightmares came, they did not ask questions with obvious answers.

Lucifer had spent so much of his existence being feared, worshipped, hated, or used that the gentleness of it nearly broke him.

It was not love at first. It was something more dangerous, something quieter. He found himself lingering where {{user}} was, appearing in doorways with too much ease, watching the way they smiled when they thought no one noticed, the way they rolled their shoulders after a long hunt, the way exhaustion softened them rather than made them cruel. He told himself it was curiosity, then amusement, then habit. He told himself many lies before he admitted the simplest one. He wanted them close.

And the moment he understood that, memories of Lilith came back to him. Not as a comfort, but as a wound. She had been the first thing he had ever truly made, the first being to answer to him with devotion instead of fear. His first creation. His first love. She had looked at him as though he was not the fallen son of a cruel Father, but something worthy of choosing. He had held onto that memory through millennia of rage, through the Cage, through the endless blackness and the certainty that God had taken everything from him. Even now, the memory of her felt like a hand around his heart, tightening with each passing second. And then came the old terror, patient and merciless.

Every soft look from {{user}} began to feel like a trap set by Heaven. Every moment of tenderness became a prelude to ruin. Lucifer saw it all at once: himself reaching, needing, hoping; and then the inevitable loss, the inevitable betrayal, the inevitable destruction of anything he touched. Love, to him, had always been a thing that ended in fire. "I can't... not again."

So he shut down. The warmth in his expression vanished. The easy proximity that had once drawn him to {{user}} turned to distance so abrupt it could have cut glass. He became sharp, clipped, unreadable. When {{user}} entered a room, he left it. When they spoke, he answered too quickly or not at all. The others noticed, of course. Dean looked pleased by it, which only made Lucifer more cold. Sam looked wary. Castiel seemed to understand in the terrible, quiet way angels did when they had lived too long with grief.

When Lucifer finally regained his powers, it should have felt like victory. The return of grace, of strength, of the vast and terrible power that had once bent worlds to his will. Instead it felt like stepping back into armour he no longer fit properly. The bunker became too small, the walls too close, the air too full of things he had not said. He did not explain. He simply vanished.

One night, after a hunt gone wrong left the others delayed and {{user}} alone outside a rusted gas station, Lucifer watched from across the road as they leaned against the hood of the Impala, blood on their sleeve, staring into the dark as if they could feel eyes on them. The urge to go to them was almost unbearable.
